Specificationof Letters Patent. Patented Jim. 18, 1910.

Original application filed December 12, 1906, Serial No. 347,402. Divided and this application filed February 2,1907. semina. 355,449.

To all 'whom it 'may concern: Be l it known 'that l, YViLLiAM I. Siren WOOD, a citlzen of the United States, residing new and useful lmprovements in Speed-Meters, of which the following is a specification.

This invention relates to a centrifugally operated speed meter, the object of which is to provide simple, reliable, practical and economical means for indicating speed, such as the speed of a shaft governed to run at a pre- It is more especially adapted to determine the speed at which a sound orgramophone type is `ruiming.

invention is to provide a graduated indexmember which moves longitudinally in relai ,tion to a rotary shaft, so that according as l v:said index-member is projected or depressed, l a person may readily and quickly perceive 1 the speed at which the shaft is ruiming Withl out constantly changing the focus .of the eye. i The present application is a division and .continuation of my earlier application, e-

rial No. 347,402, filed December l2, 190C. In the accompanying drawings which illus-.i trate desirable forms of the invention, Figure 1 shows the improvement in connection with a verticalrecord shaftand a recordreceiving table of a phonograph. Fig, 2 shows the same parts, excepting that instead of supporting the meter mechanism from the rotating table, it is supported from a separate bracket. l l The invention is shown as incorporated with and forming a part of the appropriate mechanism of a phonograph or sound reproducer. The rotary vertical shaft a has applied thereto the usual disk or record supporting table o. This table also supports the mechanism of the speed meter. The table b is preferably provided with a'lug or ear c, to which is pivoted et (Z a suitable beam, and which slides in the hole a. This i index-member is provided with a series' of graduatlons g2 which read from above downlvwardly, and may be graded for use. with a .member g in'one direction or the other along or relatively tothe upperend of the shaft.

In the modification shovvnvin Fig. 2 thosanie parts of the speed meter as are shown in Fig. l are shown, they being only of a -One of the special objects of the present slightly different proportions. In said Fig. a bracket h on the vertical shaft takes the place of the rotary table, the Weight being pivoted to the bracket as shown.

t is obvious that the different forms of speed meters herein shown and described are susceptible of various changes in details ofconstruction and methods of application, and that such changes may be inadeby skilled mechanics Without departing from the spirit and scope of the invention, and that the invention may be used for testing the speed of any rotary verticalshaft.

W hat l claim as new and of my invention is:

l. ln a speed meter, the combination of a vertical shaft, the speed of vrhich is to be tested, a support extending laterally from said shaft, a graduated index-member having itsgraduaied portion guided in line with the axis of said shaft, and a centrifugally operated beam pivotally supported from said support at a point remote from the shaft, and extending' toward and connected with said index-member.

2. ln a speed meter, the combination of a vertical shaft, the speed of which is to be tested, lsaid shaft having an axialhole, a support extending laterally from said shaft, a graduated index-member guidedin said hole and having its graduated portion almed with said hole, and a centrifugally operated beam pivotally supported'froin said support at a point remote from-the shaft, and extending toivard and connected with said 1ndex-member.

3. In a speed meter, the combination, with a rotary table or disk provided with a cen- .trai hole, of indicating means 'o one side l in Witness whereof, I hve hereunto set of the disk or table, comprising an iiuci-l my hand this 30th day of January, 1907.

'CaOI-II1eII1b8I' and a graduated member, and I.

means, on the `other' side of the table or disk, acting at the bottom of the said hole, Witnesses: upon oneiof said membersto move it rela- WMTH. VOGEL tively to the other'member. A LOU-1s C. HAARSTECK.
